Struct gstreamer::ParseContext

pub struct ParseContext { /* private fields */ }

Opaque structure.

GLib type: Boxed type with copy-on-clone semantics.

Implementations

impl ParseContext

pub fn as_ptr(&self) -> *mut GstParseContext

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GstParseContext) -> &Self

Borrows the underlying C value.

pub unsafe fn from_glib_ptr_borrow_mut( ptr: &mut *mut GstParseContext, ) -> &mut Self

Borrows the underlying C value mutably.

impl ParseContext

pub fn new() -> Self

Allocates a parse context for use with gst_parse_launch_full() or gst_parse_launchv_full().

Free-function: gst_parse_context_free

Returns

a newly-allocated parse context. Free with gst_parse_context_free() when no longer needed.

pub fn missing_elements(&self) -> Vec<String>

Retrieve missing elements from a previous run of gst_parse_launch_full() or gst_parse_launchv_full(). Will only return results if an error code of ParseError::NoSuchElement was returned.

Returns

a None-terminated array of element factory name strings of missing elements. Free with g_strfreev() when no longer needed.

Trait Implementations

impl Clone for ParseContext

fn clone(&self) -> Self

Copies the boxed type with the type-specific copy function.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ParseContext

fn default() -> Self

Returns the “default value” for a type.

impl From<ParseContext> for Value

fn from(o: ParseContext) -> Self

Converts to this type from the input type.

impl HasParamSpec for ParseContext

type ParamSpec = ParamSpecBoxed

type SetValue = ParseContext

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, ParseContext>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ParseContext

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ParseContext

fn cmp(&self, other: &ParseContext) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ParseContext

fn eq(&self, other: &ParseContext) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ParseContext

fn partial_cmp(&self, other: &ParseContext) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for ParseContext

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for ParseContext

impl Send for ParseContext

impl StructuralPartialEq for ParseContext

impl Sync for ParseContext
